Tac 20. All call lights on in COP, PI lights all on. Car unresponsive. According to IMS, car is lost due to crazy high selector count. Looking at LON explorer shows an SPI loop error on the car. STAT light on COP LON board blinking. Checked all connections, still nothing. Would you say that the COP LON board is malfunctioning and should be replaced? I should mention that the car is level at the 2nd landing, doors closed, door will reopen with the door detector but not with the door open button. all other LON nodes check out ok.
